2.2 DESCRIPTION
The Model 1070RC Synchronous Short Range Modem Rack
Card
operates full duplex, over two unconditioned twisted pair.
Supporting data rates to 19.2 Kbps, the Model 1070RC has a maximum
range of 10 miles (@ 1200 bps over 19 AWG wire). The Model
1070RC passes one control signal in each direction, and features both
optical isolation and Silicon Avalanche Diode surge protection on the
data lines side. Clocking can be sourced internally or externally.
The Model 1070RC is designed to mount in Patton's 2U high 19"
rack chassis. This 16 card chassis has a switchable 120/240 volt
power supply and mounts cards in a mid-plane architecture: The front
"brains" half-card can be plugged into different rear "interface" cards.
This means that the 1070RC card can have several interface options,
and can be switched with other Patton short haul cards.
The Model 1070RC has two built-in diagnostic tools: local and
remote loopback test. Additionally, bi-level LEDs on the 1070RC's
front panel allow you to visually monitor communication.

3.0 CONFIGURATION
This section describes the location and orientation of the Model
1070RC's configuration switches, provides detailed instructions on
setting each switch, and describes strap settings for each of the rear
connection cards.
The Model 1070RC uses a set of eight DIP switches that allow
configuration to a wide range of synchronous applications. These DIP
switches are accessible when the card is slid out of the rack chassis.
Once configured, the Model 1070RC is designed to operate
transparently, without need for frequent re-configuration.
3.1 SWITCH LOCATIONS AND ORIENTATION
The eight DIP switches on the Model 1070RC board allow you to
specify data rate, clocking method, RTS/CTS delay, and carrier control
method. Figure 2 (below) shows the orientation of the DIP switches
with respect to "ON" and "OFF" positions. The table on the following
page summarizes the switch settings, including the factory default
settings.
